Perception and neural coding of pitch through the lifespan: Peripheral and cortical considerations

Pitch is a primary perceptual attribute of our auditory world, playing a critical role in music, speech, and the organization of the auditory scene into perceptual objects. It has long been thought that stimulus timing information, conveyed by the auditory nerve, underlies and limits our exquisite sensitivity to differences in frequency, and our ability to detect very small fluctuations or modulations in frequency.

Encoding & decoding language representations in human cortex

Abstract: The meaning, or semantic content, of natural speech is represented in highly specific patterns of brain activity across a large portion of the human cortex. Using recently developed machine learning methods and very large fMRI datasets collected from single subjects, we can construct models that predict brain responses with high accuracy. Interrogating these models enables us to map language selectivity with unprecedented precision, and potentially uncover organizing principles.
